Series of P3P questions

A number of questions follow. Thank you in advance for your assistance.

1. Assume that a family of web sites has multiple domains:
www.website.com
www.website.ca ...

2. Cookies and other file types are shared across these domains such that 
www.website.ca may call / receive cookies and images from www.website.com

Would we have to include compact policies in the header of all cookies and 
images etc to ensure that they are not flagged by the browser and that 
functionality is not interrupted?

3. Majority of pages are dynamically generated such that the page is 
specified in a query string and the root URL is the same across the site:

www.website.com/some-cgi/bigdll.dll?complexvariablestring&...

How would one specify the page where particular data collection occurs given 
that 90% of the site is actually the same page, just different variables 
passed to the dll?

For example:

www.website.com/some-cgi/bigdll.dll?color&...

might ask the user to input the color they want their background to be while

www.website.com/some-cgi/bigdll.dll?creditcard&...

might ask the user to input billing information. How can one specify that 
different policies apply to these URLs given that the differentiation occurs 
in the query string? If one created a single policy for all such strings and 
some were asking for personally identifiable information what would be 
risked? Note, only cookies and images are shared across the domains, pages 
are not called across domains.

4. Where can one find a definition of Personally Identifiable Information?

Clearly this includes name, address etc. as well as userIDs where such 
apply. Is it any information that can be "mapped" back to an individual, or 
is that too specific?

That's all for now, and thank you in advance for your assistance!
